FIRSnapshotMetadata

Declaration

Returns YES if the snapshot contains the result of local writes (e.g. set() or update() calls)
that have not yet been committed to the backend. If your listener has opted into metadata updates
(via includeMetadataChanges:YES) you will receive another snapshot with hasPendingWrites
equal to NO once the writes have been committed to the backend.

Declaration

Returns YES if the snapshot was created from cached data rather than guaranteed up-to-date server
data. If your listener has opted into metadata updates (via includeMetadataChanges:YES) you
will receive another snapshot with isFromCache equal to NO once the client has received
up-to-date data from the backend.
